To all whom it may concern.'

Be it known that we, DANmL Winsnn- AoKnR and FRITZ CREMER, subjects of the German Emperor, residing at Fulda, Kingdom of Prussia, `Germany, have invented `certain new and useful Improvements in Vehicle-VV heels, of which the following is a specification.

l Wheels for motor cars `with removable- .tires of solid rubber, also such as are secured to a special iron cycle, are already known. rllhe hitherto known removable tires of solid rubber, wherein they tire is secured to an iron cycle by vulcanization, have been fastened to the rim, connected to the spokes and the hub so as to form a rigid piece, either by means of wedges orl the conical iron cycle is pressed onto the correspondingly shaped conical rim and affixed there by means of screws and the like. lt is, furthermore, known to make wheels, which are to be provided with tires of solid rubber, of such Sa design that the rim be divided into' an optional number -of segments, fastened to spokes adjustable in their length. 'ln this case the spokes had only to be shortened,4 and the tire of solid rubber.`

` mounted on ythe rim provided with lateral borders, and secured by tightening of the screws on the spokes. Hence the rubber tire .I was mainly held on therim-bv its elasticity.

The disadvantages heretofore present in the application of known forms of tires of v solid rubber may 'be avoided by making the rim consist of arigid arc-piece of approX1- mately half the circumference of the wheel, connected in the usual manner to the spokes and the.4 hub, and several other segments'.

constituting the remaining part of the rim,

each of which being adapted to be withdrawn in the usual manner into the interior of the wheel, by shortening the spokes, so`

as to grant the possibility of mounting the iron cycle of the 'tire of solid rubber on the wheel, the rim-part'sof which engage with a central, ring-shaped rib, a corresponding groove of the iron cycle.

With the present wheel about half the,

numberl of the spokes are adapted to be shortened and, together with the iron wheel, a tire of solid rubber, fixed on said iron v cycleV is employed. The 'same has the corv ided for in the rim and the cycle respectlvely insure the correct position of the tire on the rim, prevent lateral movement of the segments and the cycle itself produces a uniform distribution of the pressure.

ln the drawing a form of carrying out this invention is represented. Figure 1 shows the wheel of a motor car 1n a partly sectioned side-viewvand Fig. 2

is a cross-section according to the line A-B `screw-bolts are turned. Counter-nuts 7 in sure the affiXing. ln the embodiment of the invention shown in the drawing the iron cycle 2 has a circular groove and both the rim 3 and its parts 4 have a corresponding rib which engages the groove ofthe iron cycle.

lf the tire of solid rubber is to be eX- changed, the counter-nuts are to be loosened and the screw-bolts 5 are slackened and turned back. Hence the diameter of the rim 3 is diminished, when it is possible to remove the-tire l of solid rubber from the rim and fit a new matching tire. In this operation the iron cycle 2 and, with it,- that lof the tire of solid rubber can be secured by the arrangement of the screw-bolts 5 and the counter-nuts in such a manner that the tire of solid vrubber` is held reliably fast. The cross-groove in the iron cycle 2, which acts in common with a rib 9 in the rim, pre- 'the rim, the wheel having-spokes to which in part the said rigid arc piece is secured,

the several rim segments having annular ribs and the metal cycle formed with grooves to receive the said ribs, the spokes in line with the segments of the rim being In testimonyv whereof We have hereunto shorter than those secured to the rigid are set out hands in presence of two subserb- 1 piece of the rim, and adjusting means being witnesses.
